(3) Foundations for functions. The student formulates systems of equations and inequalities from problem situations, uses a variety of methods to solve them, and analyzes the solutions in terms of the situations. The student is expected to:

• (A) analyze situations and formulate systems of equations in two or more unknowns or inequalities in two unknowns to solve problems;

• (B) use algebraic methods, graphs, tables, or matrices, to solve systems of equations or inequalities; and

• (C) interpret and determine the reasonableness of solutions to systems of equations or inequalities for given contexts.
